24. Comprehensive Transmission Planning Process

24.1 Overview

The CAISO will develop a comprehensive Transmission Plan and approve transmission upgrades or additions using the Transmission Planning Process set forth in this Section 24. The CAISO will analyze the need for transmission upgrades and additions in accordance with the methodologies and criteria set forth in this Section 24, the Transmission Control Agreement, and the applicable Business Practice Manuals. The comprehensive Transmission Plan will identify transmission upgrades or additions needed projects associated with Approved Project Sponsors that are Merchant Transmission Facilities or are needed: (1) to maintain System Reliability; (2) to satisfy the requirements of a Location Constrained Resource Interconnection Facility; (3) to maintain the simultaneous feasibility of allocated Long-Term CRRs; and (4) as additional components or expansions to LGIP Network Upgrades identified pursuant to Section 24.4.6.5; (5) to . The comprehensive Transmission Plan will identify transmission addition and upgrade elements with no approved Project Sponsors needed to (1) meet state and federal policy requirements and directives that are not inconsistent with the Federal Power Act, including renewable portfolio standards policies; and (62) to reduce congestion costs, production supply costs, transmission losses, or other electric supply costs resulting from improved access to cost-effective resources; and (7) to reflect Merchant Facilities meeting the requirements for inclusion in the Transmission Plan. For purposes of this Section 24, the term “the year X/(X+1) planning cycle” will refer to the Transmission Planning Process initiated during year X to complete a comprehensive Transmission Plan in year X+1.

24.2 Nature of the Transmission Planning Process

The CAISO will develop the annual comprehensive Transmission Plan and approve transmission upgrades or additions and using a shall perform the CAISO’s Transmission Planning Process with three (3) phases. In Phase 1, the CAISO will develop and complete the Unified Planning Assumptions and Study Plan and, in parallel, begin development of a conceptual statewide plan. In Phase 2, the CAISO will complete the comprehensive Transmission Plan. In Phase 3, the CAISO will evaluate proposals to construct and own specific transmission upgrade or additional elements specified in the comprehensive Transmission Plan on an annual cycle in accordance with the terms of this CAISO Tariff, the Transmission Control Agreement, and the Business Practice Manual. The Transmission Planning Process shall, at a minimum:

(a) Coordinate and consolidate in a single plan the transmission needs of the CAISO Balancing Authority Area for into a single plan, which will be assessed on the basis of maintaining the reliability of the CAISO Controlled Grid in accordance with Applicable Reliability Criteria and CAISO Planning Standards, in a manner that promotes the economic efficiency of the CAISO Controlled Grid and considers federal and state environmental and other policies affecting the provision of Energy;.

(b) Reflect a planning horizon covering a minimum of ten (10) years that considers previously approved transmission upgrades and additions transmission enhancements and expansions, Demand Forecasts, Demand-side management, and capacity forecasts relating to generation technology type, additions and retirements, and such other factors as the CAISO determines are relevant;.

(c) Seek to avoid unnecessary duplication of facilities and ensure the simultaneous feasibility of the CAISO Transmission Plan and the transmission plans of interconnected Balancing Authority Areas, and otherwise coordinate with regional and sub-regional transmission planning processes and entities, including interconnected Balancing Authority Areas,. in accordance with Section 24.8;

(d) Identify existing and projected limitations of the CAISO Controlled Grid’s physical, economic or operational capability or performance and identify transmission upgrades and additions, including alternatives thereto, deemed needed in accordance with Section 24.1 to address the existing and projected limitations;.

(e) Account for any effects on the CAISO Controlled Grid of the interconnection of Generating Units on the Distribution System under the Wholesale Distribution Access Tariffs of the Participating TOs, including an assessment of the deliverability of such Generating Units in a manner consistent with CAISO interconnection procedures. on a basis comparable to the Deliverability Assessment performed under Appendix U or Appendix Y, as applicable.

24.3.4 Economic Planning Studies

24.3.4.1 CAISO Assessment of Requests for Economic Planning Studies

Following the submittal of a request for an Economic Planning Study, the CAISO will determine whether the request shall be designated as a High Priority Economic Planning Study for consideration in the development of the comprehensive Transmission Plan. In making the determination, the CAISO will consider:

(a) Whether the requested Economic Planning Study seeks to assess Congestion not identified or identified and not mitigated by the CAISO in previous Transmission Planning Process cycles;

(b) Whether the requested Economic Planning Study addresses delivery of Generation from Location Constrained Resource Interconnection Generators or network transmission facilities intended to access Generation from an Energy Resource Area or similar resource area assigned a high priority by the CPUC or CEC;

(c) Whether the requested Economic Planning Study is intended to address Local Capacity Area Resource requirements;

(d) Whether resource and Demand information indicates that Congestion described in the Economic Planning Study request is projected to increase over the planning horizon used in the Transmission Planning Process and the magnitude of that Congestion; or

(e) Whether the Economic Planning Study is intended to encompass the upgrades necessary to integrate new generation resources or loads on an aggregated or regional basis.

24.3.4.2 Selection of High Priority Economic Planning Studies

In accordance with the schedule and procedures set forth in the Business Practice Manual, the CAISO will post to the CAISO Website the list of selected High Priority Economic Planning Studies to be included in the draft Unified Planning Assumptions and Study Plan. The CAISO may assess requests for Economic Planning Studies individually or in combination where such requests may have common or complementary effects on the CAISO Controlled Grid.
